Product Description

Whether you are listening to some tracks, or tracking your next recording, the KNS 6400 gives you the famous KRK sound independent of your monitors. This closed-back around-the-ear design brings you closer to your music, and the highly isolated surround pads give you the freedom to immerse yourself in the sound without having your monitor mix "escape" into open microphones -- and keeps live instruments out of what you are monitoring. Having "One Voice" that consistently gives you accurate reproduction of your music or mix will help you achieve just what the artist intended -- especially if the artist is you.

Overall:
I bought a pair of these headphones from Guitar Center over a year ago just to try them out. I found myself taking them on the road with me all the time, instead of my Bose noise canceling headphones. When I received an email for discounted B stock from ZZounds, I figured I would upgrade some of my worn out studio phones. I bought four pair. Handed a box to a client, whom I've don't three CDs with. She did a vocal track and said "wow, these are very focused, I can hear myself really well". No more needs to be said as far as I'm concerned. These are very good headphones for the money. they are light, comfortable, and sound very natural. I like them.

Thank you. Your vote has been counted. Could you briefly tell us why the review was or was not helpful?

"Good for laying tracks but not for final mixdown."

Sound:
I bought these headphones because I've read that KRK makes one of the best sounding studio monitors so I figured their headphones must be great as well. The clarity is awesome with these headphones. I compared them to an extremely old pair of AKG headphones I have, which still work really well, and the KRK's output is a little louder and my highs and mids are clearer. The only I do NOT like about the KRK's is they lack bottom end. After doing a mix of a couple instrumentals and playing them back on my home and car stereo systems, my bass track was way over powering. On that note (no pun intended) these phones are good for laying down tracks but I would not recommend them for final mix downs.
Feature:
I DO like the fact that the cable can be disconnected from the headphones (it comes disconnected). So if the cable ever went bad you don't have to repalce your entire headphone set. Cool feature.
Ease of Use:
Simple...plug in and play. Works great with my interface (Presonus AudioBox).
Quality:
Again, the clarity is excellent but there's not enough pronounced bottom end which really messes me up on mix downs. I have a small home studio setup in an apartment so I can't crank up monitors for mixing so I rely mostly on headphones. But overall for laying initial tracks, they're great and they seem sturdy as well.
Value:
For the price these are a decent set of studio phones. I'm now wishing i would've went with the next step up though.
Overall:
As stated, my main issue with these phones is the lack of bottom end. Other than than, I'm satisfied with them.
